1. The OLED screen in the room lights up and cycles through sensor data and instructions to interact with the room
2. Giana presses a button and the fan turns up
3. Giana turns off the light in her real living room and the light in the Firebase room turns on
4. Giana turns the knob and music starts playing on the piezzo
5. Giana opens and closes the door and the music stops and the light turns off.
6. Giana notices a message "open in Firebase" w/ a bar code on the OLED screen.
7. Giana scan the bar code with her phone and is taken to a demo Firebase
8. Giana can see all the sensors data and actuator states in the "Data" section.
9. Giana pushes the button in the room and sees a new timestamp being inserted under the 'events' key.
10. Giana changes the "light" property to "1" and it turns on the light.
11. Giana changes the "light" property to "0" and it turns off the light.
